Yes you are liable for paying him half. Misappropriation of funds or wasting. Best thing is to wait it out and hope he doesn’t sign or have him cancel the divorce if he does till things clear. There was previously a 5 year look back but it
May now only be 2 years. My soon to be ex wife did this and my attorney said she had to put it back or pay half. Divorce will be inevitable at this point.
